Elements 1 and 3
Print element 1 and element 3 of the array x
For the array [2, 7, 5, 3] you should print 7 and 3
Element 0 is 2, element 1 is 7, element 2 is 5, element 3 is 3.
Add the first two
Print element 0 add element 1 of the array x
Element zero is x[0], element one is x[1]. Add these two values and print the result.

Notice that the last index is x.length-1
Add the first and the last element
Print the first item plus the last item of the array.
